80% band, log scalemid, reviews × k

Owners ≈ reviews × k: 68,064 × 60 = 4,083,840. k is the prior for 2013 and earlier, because no cell in that band has five announced figures. The band applies the model’s own residuals (10th to 90th percentile, ×0.40 to ×2.28 of the mid); over 144 announced figures the model is typically within ×1.5 and 79.2% of them fall inside the band. Model OWN-1, calibrated 6 Sep 2026. How this is computed. Data by SteamPeaks.com.

One daily sample so far (6 Sep 2026); the line draws with the second.

Followers are the community hub’s member count as the store page shows it, sampled by SteamPeaks since 6 Sep 2026. A gain is the newest sample minus the sample the window back (within twelve hours for one day, a day otherwise); where that older sample does not exist the gain is missing, never zero, and the day the window opens is given instead. Figures from the hourly momentum job, run 7 Sep 2026, 03:34 UTC. No follower-to-wishlist ratio is applied. How this is computed. Data by SteamPeaks.com.
